Self-esteem and formality of instructions as variables influencing selective recall

The present study attempted to determine whether the selective recall phenomenon was related to self-esteem. The selective recall phenomenon is the inferior recall of interrupted tasks in a formal (ego-threatening) situation, relative to the recall of interrupted tasks in an informal (nonthreatening) situation. Two hundred eleven college students responded to a self-esteem inventory and then were given formal or informal instructions. They then worked on 16 tasks, and were interrupted on 8 but were allowed to complete 8. Finally, an unexpected free-recall test of task solutions was administered. Only subjects low in self-esteem exhibited the selective recall pattern. It was hypothesized that in a formal situation, interrupted activities were viewed as failures. It was assumed that the recall of failures was particularly threatening to low-self-esteem subjects, resulting in selective forgetting or selective storage of solutions. It was also found that all subjects recalled solutions from completed tasks more frequently than solutions from interrupted tasks. Several interpretations for the latter phenomenon were suggested, including a dual mechanism involving both motivation persistence and motivation reduction, and the incorporation of information into a self-referent schema.     

Pupillary and heart rate reactivity in children with minimal brain dysfunction

This study attempted to replicate and extend previous findings on autonomic arousal and responsivity in children with diagnoses of minimal brain dysfunction (MBD). Pupil size, heart rate, skin conductance, and skin temperature were recorded from 32 MBD and 45 control children during a session that included presentation of visual stimuli, simple reaction time (RT), a cold pressor procedure, and rest periods. The MBD children were tested both off and on clinical dosages of stimulant drugs in a crossover design. Evidence of higher than normal arousal levels in the unmedicated MBD Ss was obtained from resting skin conductance and, more tenuously, from pupil size. Lower phasic responsivity in the MBD children was evidenced by slower RT, less cardiac deceleration to both light and RT stimuli, and smaller pupil dilation to the RT stimuli. Spontaneous pupillary constrictions during rest periods, presumably indicating drowsiness, were observed about equally in MBD and control children. Stimulant drugs raised arousal levels but did not reverse the responsivity deficits. The lower phasic reactivity in the MBD group and the effects of stimulant drugs on arousal indices confirm earlier reports. The finding of higher arousal in drug-free MBD children is incompatible with the low arousal hypothesis of MBD but is consistent with a previous report of the effects of a stimulating environment on these children.This work was supported in part by a grant from the Ittleson Family Foundation.

Note on locus of control and academic achievement in institutionalized juvenile delinquents

The previously reported relationship between internal locus of control and academic achievement was explored with the Nowicki-Strickland Locus of Control Scale for Children (Nowicki & Strickland, 1973) and seven measures of academic achievement in a random sample of 45 male residents of seven state learning centers for juvenile delinquents. Correlations between overall locus of control scores and all seven measures were significant, but with intelligence controlled in a partial correlation, locus of control scores were found to add little to the prediction of academic achievement from IQ scores alone. Discussion addressed possible explanations for the current findings in terms of the meaning of the scale for a nonnormal group and the effects of situations on responses of subjects.Appreciation is expressed to Mobile Psychiatric Clinic staff psychologists, to the U.S. General Accounting Office, and to Kingsbury Center, consultants, Washington, D.C., for their assistance in data collection.     

Integrating the ethical and social context of computing into the computer science curriculum

This paper describes the major components of ImpactCS, a program to develop strategies and curriculum materials for integrating social and ethical considerations into the computer science curriculum. It presents, in particular, the content recommendations of a subcommittee of ImpactCS; and it illustrates the interdisciplinary nature of the field, drawing upon concepts from computer science, sociology, philosophy, psychology, history and economics.     

A comparison of subset selection and analysis of covariance for the adjustment of confounders

Two common methods for adjusting group comparisons for differences in the distribution of confounders, namely analysis of covariance (ANCOVA) and subset selection, are compared using real examples from neuropsychology, theory, and simulations. ANCOVA has potential pitfalls, but the blanket rejection of the method in some areas of empirical psychology is not justified. Assumptions of the methods are reviewed, with issues of selection bias, nonlinearity, and interaction emphasized. Advantages of ANCOVA include better power, improved ability to detect and estimate interactions, and the availability of extensions to deal with measurement error in the covariates. Forms of ANCOVA are advocated that relax the standard assumption of linearity between the outcome and covariates. Specifically, a version of ANCOVA that models the relationship between the covariate and the outcome through cubic spline with fixed knots outperforms other methods in simulations.     

The varying value of a friendly face: Experimentally induced stress is associated with higher preferences for friendship with people possessing feminine versus masculine face traits

Social support can provide a buffer to the negative consequences of stress. Previous research suggests that stress can promote affiliative and cooperative behaviours in those who are stressed. Here we examined how stress might influence who we choose to affiliate with. We measured preferences for friendships with friendly appearing feminized faces versus less friendly appearing masculinized faces after individuals undertook a stressful laboratory task. Stressed individuals had increased preferences for friendships with people with feminine faces. These data demonstrate that individuals prefer more friendly appearing feminine faced people as friends when stressed than when not stressed. This preference is likely adaptive in directing individuals towards others who are most likely to provide social support when it is needed and so reflect strategic friendship preferences.     

Dissociating averageness and attractiveness: attractive faces are not always average

Although the averageness hypothesis of facial attractiveness proposes that the attractiveness of faces is mostly a consequence of their averageness, 1 study has shown that caricaturing highly attractive faces makes them mathematically less average but more attractive. Here the authors systematically test the averageness hypothesis in 5 experiments using both rating and visual adaptation paradigms. Visual adaptation has previously been shown to increase both preferences for previously viewed face types (i.e., attractiveness) and their perceived normality (i.e., averageness). The authors used a visual adaptation procedure to test whether facial attractiveness is dependent upon faces' proximity to average (averageness hypothesis) or their location relative to average along an attractiveness dimension in face space (contrast hypothesis). While the typical pattern of change due to visual adaptation was found for judgments of normality, judgments of attractiveness resulted in a very different pattern. The results of these 5 experiments conclusively support the proposal that there are specific nonaverage characteristics that are particularly attractive. The authors discuss important implications for the interpretation of studies using a visual adaptation paradigm to investigate attractiveness.     

Social-identity functions of attraction to organizations

This article examines the self-presentation goals that underlie attraction to organizations. Expanding on Lievens and Highhouse’s (2003) instrumental vs. symbolic classification of corporate attributes, a theory of symbolic attraction is presented that posits social-identity consciousness as a moderator of the relation between symbolic inferences about organizations (e.g., this company is dynamic and innovative) and attraction to those organizations. A measure of social-identity consciousness is developed, and a series of studies confirmed two dimensions, labeled concern for social adjustment and concern for value expression. Preliminary evidence supports the validity of the measure and its role in moderating attraction to symbolic features of well-known firms.
